Astronomers have successfully taken high-quality images using a ground-based telescope at Dome C, Antarctica, which rivals the capabilities of the Hubble Space Telescope. The site offers excellent seeing conditions and low atmospheric interference, making it an attractive alternative to space-based astronomy.
Astronomers at Yale University have discovered the most distant object in our solar system, Sedna, which is approximately 10 billion miles away from the sun. Sedna's orbit ranges from seven to 100 billion miles from the sun and its characteristics are consistent with it residing in the Oort cloud.
The Gemini Deep Deep Survey has revealed a greater abundance of more massive and older galaxies than expected, dating back to the early universe. The discovery challenges current models of galaxy formation and suggests an accelerated growth phase for galaxies.
Researchers studied two binary star systems, predicting regular flare cycles similar to the Sun's magnetic cycle. The team used continuous monitoring of radio waves to discover patterns in flare strength, indicating active and inactive cycles every 50-120 days.
The $18 million SALT Observatory is nearing completion and will feature the largest optical telescope in the Southern Hemisphere. The observatory's primary scientific instrument, a spectrograph, will break light down into its constituent wavelengths to study stars and galaxies outside of the Milky Way.
The SIRTF is designed to peer into deep regions of the universe not visible optically, providing clues to star and galaxy formation. With its infrared spectrograph, it will observe ultrafrigid stars and penetrate obscuring dust in the cosmos.
The University of California, Berkeley's robotic telescope has captured the earliest image of a gamma-ray burst's optical afterglow, offering unprecedented data for theorists to study. The data provides key constraints for physical models of gamma-ray bursts and will help astronomers better understand these enigmatic events.
Researchers have developed a synthetic guide star system that can correct for atmospheric turbulence in about three fifths of the sky, opening up a much larger portion of the heavens for study. The system uses laser beams to create artificial stars, providing high-quality images of planets, galaxies, and other objects.
The Gemini Observatory has dedicated its second telescope, Gemini South, marking a decade of work by hundreds of people to build two advanced 8-meter instruments. Astronomers in the US and around the world now have access to unprecedented sky coverage.
CU-Boulder joins a powerful 3.5-meter telescope consortium in southeastern New Mexico, providing the department with its first facility for ground-based observational astronomy. The university has invested $330,000 of its own money and secured private funding to participate in the consortium.
Scientists have successfully observed an optical coronal line from iron ions in a star called CN Leonis, located 8 light-years away. This achievement marks the first time such a detection has been made outside of our solar system and opens up new avenues for studying stellar cycles.
At the American Astronomical Society meeting, NSF highlighted recent breakthroughs in adaptive optics, revealing a solar-system-sized disk around a massive protostar. The NOAO Deep Wide-Field Survey also captured 300,000 faint galaxies over a vast area, creating the first three-dimensional map of the universe.
A 6.5m telescope mirror is transported from the US to Chile's Atacama Desert, renowned for its stable and dry atmosphere, to conduct astronomical observations. The mirror will be installed as part of the Magellan Twin Telescope project at the Las Campanas Observatory, enabling studies of the Milky Way, star formation, and the universe.
The Chandra X-ray Observatory has been selected as one of the top 100 'Best of What's New' items by Popular Science magazine, highlighting its significant contributions to X-ray astronomy. The observatory is already sending back impressive images that are aiding in understanding exploding stars, black holes, and other celestial phenomena.
The UNC-CH physics and astronomy department has launched a new program called SOLAR, which allows North Carolina public school teachers and students to use and remotely control the Morehead Observatory telescope. The program offers students access to real scientific data and the opportunity to capture their own images of the universe.
FORCAST, a new infrared camera, will be built at Cornell to image the universe in the infrared spectrum and study stars' neonatal environments. The instrument will fly aboard NASA's Stratospheric Observatory for Infrared Astronomy (SOFIA) and make observations that are impossible for ground-based telescopes.
The Katzman Automatic Imaging Telescope (KAIT) is a fully robotic telescope that can track a given area of the sky for hours and detect objects 10,000 times fainter than other telescopes. KAIT will enable astronomers to conduct nightly studies of changing celestial objects remotely.
